Which of the following is one of the six pollutants under Kyoto Protocol regulations?

  1. A.Chlorine
  2. B.Phosgene
  3. C.Carbon monoxide
  4. D.Perfluorocarbons

Correct answer

D. Perfluorocarbons

Explanation

The correct answer is D, Perfluorocarbons. The Kyoto Protocol, adopted in Japan in December 1997 and in force from February 2005, set binding cuts for six greenhouse gases: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride. Perfluorocarbons come mostly from aluminium smelting and from making semiconductors; they are released in tiny amounts but survive in the atmosphere for thousands of years and trap far more heat than the same weight of carbon dioxide, which is why the Protocol counted them. Nitrogen trifluoride was added as a seventh gas later, under the Doha amendment of 2012. A is wrong because chlorine is not a greenhouse gas; chlorine released from CFCs harms the ozone layer, a matter the Montreal Protocol deals with. B is wrong because phosgene is a poisonous industrial gas and is not on the Kyoto list. C is wrong because carbon monoxide is an air pollutant that the Protocol does not cover. Exam tip: the six Kyoto gases are carbon dioxide, methane, nitrous oxide, HFCs, PFCs and sulphur hexafluoride.
